VEGETABLE-CUTTER.

. Application filed April 14, 1915.

T all whom it may concern:

Be it known that I, ADoLPH STOLTENBERG, a subject ofthe Emperor of Germany, re-

siding at New York, in the county of New York and State of New York, have invented new anduseful Improvements in Vegetable Cutters, of which the following is a specification.

This invention relates to a vegetable cutter and has as its principal object to provide a device by means of which different kinds of vegetables, such as potatoes, onions, carrots, etc, maybe cut up intopieces of various shapes and sizes.

proper way, without crushing, so that the vegetables cut up and put into water may be preserved for use on the next day, without detriment to their outward appearance or taste which cannot be done when the vegetables are crushed in the iprocesspf cutting them up as is the case in existing machines.

. A still further object is theelimination of waste in material.

With the foregoing and other objects in view, my invention consists in the particular arrangement, combination and construction of parts, more specifically described hereinafter and illustrated in the accompanying drawings, in which:

Figure l is a side elevational view of my device. Fig.2 is a front elevational view thereof. Fig. 3 is a fractional side elevational and Fig. 4 a fractional rear elevational view of the same on an enlarged scale. Figs. 5 and 6 are front and side elevational views, respectively,of a part of my device.

Figs. 7 and 8 show a detail of the part illustrated in Figs. 5 and 6, inside and front elevation, respectively- Figs. 9 and 10 are frontand side-elevational views, respectively, of another part of my device. Figs. 11 and 12 are" similar views of still another part of same. Fig. 13 is a rear elevational view and Fig. 14 a vertical cross-section of a handwheel forming. part of my device. Figs..15 and .16, 17 and 18, 19and 20 are rearand side-elevational views, respectively, of different parts of my device.

The same reference character designates the same part throughout the several views.

Specification of Letters Patent.

With my device'this object can be accomplished in a clean and Patented Oct. 19, 1915.

Serial No. 21,288.

Referring more particularly to the drawings, 21-21 are pedestals formed integrally with the semi-cylindrical lower part 22 of a casing 23, completed by an upper part 24 of substantially the same shape, but having, near its fore end, a substantially semi-spherical hopper 25 formed in it, through which the vegetables are fed into the cutter. The two parts 22 and 24 of the casing 23 are secured together by means'of bolts and nuts as is obvious from the drawings and is best seen at 26 in Fig. 4.

The front end of the casing 23 is open and has a square shouldered portion 26 formed thereon, having a vertical groove 27 in each side (Figs. 1 and 2), adapted to engage the flanges 28 of a square frame or I knife-holder 29 carrying a plurality of sawtoothedknives 30 set in it alternately with teeth pointing downward and upward, as best seen in Fig. 6. The knife-holder 29 may be inserted into the shouldered portion 26 with the knives 3O horizontal or vertical, for purposes which will hereinafter appear.

Mounted at the front of the portion 26, near the longitudinal center of its lower edge, is a vertical bracket 31 having two horizontal arms and carrying, removably secured between two set screws 32 journaled into them, a vertical cylinder 33 provided with a plurality of rigid horizontal cuttingdisks 34 in front of and close to the opening 35 of the casing 23. An oblique knife 36 is further provided in front of the opening 35, adapted to slide laterally between same and the cutting-disks 34 and secured to a hori' zontal rack 37 carried by a horizontal bar 38 formed at the bottom of the portion 26. The rack 37 has a dovetailed tongue 39 formed at its top, adapted to slide in a correspondingly shaped groove formed in the bottom of the bar 38, all along its length.

The rack 37 is reciprocatingly actuated by a toothed segment 40 rigidly mounted on the fore end of a shaft 41 journaled into the pedestals 2121, on the rear end of which is rigidly mounted a crank-lever 42 having a handle 43 near its upper end by means of which the crank-lever 42 may be swung to and fro, thereby actuating the whole device, as will hereinafter appear.

Within the casing 23 I provide a disk- I shaped pusher 44 shown in detail in Figs. 9 and 10, having formed, in its front surface, both horizontal and vertical notches 45 registering with the knives 30 in either of the two alternativepositions in which same may be inserted in the cutter. The pusher 44 has integrally formed thereon two center, projecting backward therefrom, a

hub 50. A spirally threaded bore 51 is provided inthe hub 50 and the cross-piece 49,

- adapted to receive therein and be engaged pose of which willbe set forth hereinafter.

bya spiral worm 52 carried by the front end of a shaft 53 journaled in the rear end of the casing 23 and projecting therethrough. The shaft 53 has, adjacent to the inner surface of the rear wall of the casing 23, a

flange or washer 54 serving to keep it in" place. Thus'when the shaft 53 is rotated in one or the other direction, the worm-gear will cause the pusher 44 tomove back or forth, as the case may be.

On the part of the shaft 53 whichprojects outward of the casing 23. is rotatably mounted a lever 55 having a "longitudinal slot; 56 made in its stem, engaged by a pin 57*secured to the stem of the crank-lever 42. .Thus when the latter is moved to and fro, the lever 55 is actuated thereby in an obvious manner. On the lever 55 is formed, near its hub-portion,' a projection 58 to which is hingedly attached a pawl 59 kept in en'gagement, by means of a spring 60, with a ratchet-wheel 61 rigidly attached to the shaft 53 by means of a tongue 62 and groove 63. The casing 23 has, at its rear end, a reduced portion 64 on which is mounteda ring 65 provided with a slot 66 through which projects a pin 67 threaded at bothrends, one end being screwed into the reduced portion 64 and the other adapted to receive thereon a winged nut 68. Owing to this arrangement, the position of the ring 65 on the reduced portion 64 issusceptible of "variation within certainlimits the pur-:

The ring 65 has hingedly attached to a projection 69 thereof a pawl 70 normally kept in engagement with the ratchet wheel 61 my means of a spring 71. The ring/65 has also formed on its rear surface a'tapering projection 72 overhanging the ratchet wheel-61 and so pawl 59' that thelatter is forced to mount its declivity and thus get out of engagement with the ratchet wheel "61 when traveling over same in the direction indicated by an arrow in: Fig. 17. When traveling in the contrary direction, the pawl 59 engages "the ratchet wheel 61 onlywhen it gets off the slide-bars 46- projecting backwardtherefrom, one on either side, their outer surface correspondlng in shape to thelnner thrust of the pusher '44 at each swing placed in respect to the rlng 65 in respect to the pawl 59 is susceptibio of modification by means of the winged nut 68 and associated mechanism, there is a certain latitude given in determining 'at what part of the circumference of the ratchet wheel 61 the pawl 59 should engage it at each movement of the lever 55 whereby the extent of rotation of the ratchet wheel 61 and ofthe shaft 53"on which it is rigidly mounted, maybe regulated. It will be ob- V vious from the foregoing that by moving the ring 65 to different positions in respect to the pawl '59 the distance of the forward the lever 42 (carrying withit the lever 55) a may be regulated. 1

As will be seenin'FigL4, the crank lever 42 is formed, at aboutits longitudinal center, into a double arc extending-right and left, thereby forming aslot within which the shaft 53 is-comprisedso as not to inter fere with the operation ofthe crank lever 42. r I r A hand-wheel 7 3 is rigidly mounted on the rear end of the shaft 53, for the purpose of rotating the latter in a sense contrary to 1 that produced by the actuation of'the lever 55 thusrmove th 'p h 4:4:

when required. The

backward, must be forced. out of engage pusher 44 back. I r

The operationof my device is as follows;

pawl which nor-l" .mally prevents the shaft 53fto be turned Thevegetables are'fed into the casing 23 through the hopper .25 whenthe' pusher 44 isin' a position at the'rear of the hopper. The crank-lever 42 is then swung to and fro by the handle 43 which causes the ratchet-coupling described to "rotate the shaft 53 and the spiral worm 52 attac'hed'to it, thereby moving the pusher' 44 forward in 5 an obvious manner. The vegetables will 30'and afterpassing through them, against the cutting disks 34, whereafter the intermediate oblique knife reciprocatingly actu ated by thetoothed segment "40 in the manner before described-will cut in trans-1 versely. As the knives30' are adapted to,

enter the notches made in the front surface of the pusher 44, the latter can, :by successively being actuated,be' moved quite up to the front opening of the casing 23 and thus push out the entire 'piecejof vegetable from same. Whenthis isdone, the pusher 44 is By arranging the knives 30 verti cally or horizontally and byremoving or leaving in place the cylinder 33 with the cutting disks 34 and of the oblique knife 36, thevegetables may be cut up into a very numerous variety 11c thereby be pushed firstagain'stithe knives i of shapes and sizes. The shape may further be variegated by providing frames 28 with diagonally arranged knives 30, or with knives bent in different ways so as to pro duce any desired fancy shape of the finished product. It will also be understood that by regulating the extent of the forward thrust of the pusher 44 at each movement of the levers, I regulate the size to which the vegetables are cut up by the oblique knife 36.

The fact that the vegetables are first pressed against one set of knives and then against the other, prevents their being crushed as is the case when they are pressed simultaneously against two sets of transverse knives. The pressure is further diminished by the. formation of saw-teeth in the knives 30 and by alternating them with teeth pointing upand down-ward, so that they enter the vegetables gradually and not. with the whole edge at the same time. The

circular shape of the edges of'the cutting disks 3% serves the same purpose.

It is understood that while I have thus described and shown the-preferred form of embodiment of my invention, I do not want to be limited to the mechanical details thereof, but may resort to such alterations and modifications as come within the scope of the claims hereunto appended.

I claim: 7

1. A vegetable-cutter comprising, in combination, a casing, a set of interchangeable cutting means adapted to be removably inserted in thefront opening of said casing,

another set of cutting means removably mounted in front of said opening, a detachably mounted reciprocating knife adapted to cut in transversely between said first and second-mentioned sets of cutting means, means for feeding vegetables into said casing, means for pushing same against said cutting means in succession and means actuating said pushing means simultaneously against said cutting means in succession,

means actuating said pushing means simultaneously with said reciprocating knife, and -means for regulating the extent of the forward thrust of said-pushing means at each successive operation.

In testimony whereof Ihave hereunto set my signature in the presence of two witnesses.
